## On the Speed of Rotation of the Isotropic Space: Insight into the Redshift Problem

**Authors:** Dmitri Rabounski

This study applies the mathematical method of chronometric invariants, which are physically observable
quantities in the four-dimensional space-time (Zelmanov A.L., Soviet Physics Doklady, 1956, vol.1, 227-230).
The isotropic region of the space-time is considered (it is known as the isotropic space). This is
the home of massless light-like particles (e.g. photons). It is shown that the isotropic space rotates
with a linear velocity equal to the velocity of light. The rotation slows in the presence of gravitation.
Even under the simplified conditions of Special Relativity, the isotropic space still rotates with the
velocity of light. A manifestation of this effect is the observed Hubble redshift explained as energy
loss of photons with distance, for work against the non-holonomity (rotation) field of the isotropic
space wherein they travel (Rabounski D. The Abraham Zelmanov Journal, 2009, vol.2, 11-28). It is shown
that the light-speed rotation of the isotropic space has a purely geometrical origin due to the space-time
metric, where time is presented as the fourth coordinate, expressed through the velocity of light.
